Patent CA-2136617-A1 (CA)
Title: Auxiliary Video Data Slicer
Inventor: SCHULTZ MARK A
IPC: H04N7/03
Filed: 1993-05-28
Abstract: An auxiliary video data slicer for extracting auxiliary video information in a video signal includes a peak detector (220, 230) for determining the peak amplitude of horizontal sync pulses and of a run-in-clock (RIC) waveform included in the auxiliary video information. A variable threshold voltage (PEAK VREF) for the peak detector is varied in a first range to detect the sync pulse peak. A threshold voltage (SYNC VREF) for detecting the leading edge of sync pulses is derived from the peak amplitude of the sync pulses. The location of the RIC waveform interval within a particular line of video is determined based on the detection of a sync pulse edge (SYNC). The variable threshold voltage is varied in a second range to detect the peak amplitude of the RIC signal. A data slicing threshold level (DATA VREF) for extracting auxiliary video information is derived from the peak value of the RIC signal. The auxiliary video data slicer may be implemented in an integrated circuit.

Abstract: An improved handle-to-deck coupling arrangement for a lawn mower.  The coupling arrangement is provided in part by a lawn mower handle having a pair of curved distal end portions.  The distal ends portions fit within a pair of channels integrally formed in a deck of the lawn mower.  The end-most portions of each distal portion of the handle fit within sockets formed in a lower-most portion of the deck.   This coupling arrangement serves to spread out stresses experienced by the deck over a larger area of the deck when pushing or lifting forces are exerted on the handle member by an operator.   In a preferred embodiment, an anchor-type fastening assembly is included.  The anchor-type fastening assembly is associated with at least one of the sockets and provides a plurality of arm portions which fit within an interior area of the end-most portion of the handle member once the end-most portion is inserted in the socket.  The arm portions may then be expanded radially outwardly into contact with an inner surface wall of the end-most portion of the handle member by advancing a threaded fastener into the area defined by the socket.   When completely advanced, the threaded fastener urges the arm portions radially outwardly, thus locking the end-most portion in the socket.
